Methods Arachnoid cells of human were planted in 25 cm2 Falcon flask and the characteristics of cultured cells were observed by inverted phase contract microscope.

This study was undertaken to explore the inducing effects of retinal cells of rat neonates on differentiation of bone marrow mesenchymal cells(BMSCs) into RGC-like cells.

Purpose:To analyse the differentiation features of embryonic stem cells which were induced by the supernatant of retinal cells and retinoid acid (RA).

In vitro differentiation of embryonic stem cells induced by retinoid acid and co-culture of retinal cells;

Changes of the level of vitreous nerve growth factor and retinal cells after retinal detachment in rabbit;

Effects of Shihusan on human retinal cells cultured in vitro

An ommatidium is composed of transparency area and photonasty area;the transparency area is made up of cuticular cone and aperture,but photonasty area includes retinular cells and a lot of pigment cells.

CT research of the depression of occipital arachnoid granulations;

AIM To study characteristics of the images and clinical features of arachnoid cyst in the sacral canal in order to improve our ability to diagnose it.

Methods: Observing 78 cases\' pathologic changes of the trigeminal nerve\'s roots(the nerve\'s roots,arachnoid,reponsible vessels and the interreaction among them) by operative microscope in the microvascular decompression and arachnoid relax surrounding nerve root of the primary trigeminal neuralgia.
